Truth can be ascertained in regard to how well our bodies are working with the realities of creation. We are a complex system of chemicals interacting with each other. What we believe and know about reality will incite our bodies to react in different ways as a result. When our knowledge about reality is skewed, our wellbeing is out of sync with the world around us. Medications, in regard to reactions resulting from reason and logic, seek to block or substitute our chemical reactions to create a wellbeing apart from our illogical understanding of reality.
